实验步骤: 3-(ethoxymethylene)pentane-2,4-dione (Preparation 2, 8.6 g) was dissolved in Ether (30 mL) and cooled to 0° C. The reaction solution was then slowly treated with 1-methyl-2-(propan-2-ylidene)hydrazine (Preparation 1, 4.8 g) dropwise over 5 minutes, and then warmed and stirred at room temperature overnight. The reaction solution was purified directly by flash column chromatography (Biotage Quad 25; Eluent: 20% EtOH in EtOAc) to afford the title compound as a light red solid. (9.1 g, 84.0%). warmed The reaction solution was purified directly by flash column chromatography (Biotage Quad 25; Eluent: 20% EtOH in EtOAc)
